EYE-PROTECTOR.

Specification of Letters Patent.

Patented Mar. 25, 1919.

To all whom t may concern.'

Be it known that I, HOWARD T. REEVE, of Southbridge, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Eye-Protectors, of which the following is a specification.

This invention relates to improvements in eye protectors, and has particular reference to a new and improved form of transparent visual member for use in devices of this character and to a novel and improved means of forming such visual member.

Une of the leading objects of the present invention is the provision of an improved reinforced ylens or visual member particularly adapted for use int goggles or eye protectors for aviators or the like which will be so constructed as to bind the lens together and prevent fiying `particles of glass entering the eye.

A further object of the present invention is" the provision of an improved lens or the like whereby an extremely desirable transparent visual member is obtained having substantially the transparence and surfaces of a -polished member such as glass combined with the toughness or infrangibility of mica, Celluloid or similar substances and which will therefore afford perfect vision combined with safety of the eye from flying particles either of the lens itself or from particles not having great striking velocity piercing the lens.

Other objects and advantages of my improved construction should be readily l understood by reference to the following specification taken in connection with the accompanying drawings, and it will be understood that I may make any modifications in the specific details of construction shown and described within the scope of the appended claims without departing from or exceeding the spirit of my invention.

Figure I represents a View of my improved construction in use.

Fig. II represents a detailed View of one of my lenses.

Fig. III represents a sectional View thereof on the line III-III of Fig. II.

'Fig. IV represents a view illustrating the forming of my improved visual member.

Fig. V is a similar view illustrating4 the formation of a modified form thereof, and

Fig. VI represents a sectional View of another modiication.

In the drawings, in which similar characters of reference vare employedto denote corresponding parts throughoutV the several views, the numeral l denotes the frame in which my improved lenses are held, said frame inthe particular style illustrated having the side shields 2 to fit against the face of the wearer and being further provided with the short temple members 3 to which are secured the ends of the head band 4 for retaining the frame in position on the face of the wearer, there preferably being a pair of the lens frames centrally connected as by the bridge member 5 to permit the frame to automatically fit itself to the face of the wearer without any special adjustments.

It will be noted by reference to the drawing that my improved protection lens is especially adapted for use in eye protectors for aviators or the like where the wearer requires as perfect vision as possible and yet a lens which will be relatively infrangible and which if struck will not y off in particles liable to pierce and injure the eye, but which on the other hand will not only itself cling together and not shatter but which will resist accidental piercing and will tend to stop such particles and prevent their striking the eye of the wearer.

In the accomplishment of these results, I have provided an improved lens preferably -comprising a transparent-member 6 of glass or similar material which may if desired be polished to an extremely smooth surface, while combined with said hard transparent member is a film, layer or coating also of transparent but of flexible or non-frangible material which will resist breakage or piercing. This film or layer 7 may be placed on the eye side only of the lens in order to hold the fragments of the lens proper together i-f shattered and prevent flying chips from breaking off the rear face and striking the eye, or may 'be placed on both the inner and outer faces if preferred, one form being illustrated in Fig. IIIwhile the other form is shown in Fig. VI. In either event it is to be noted that the layer 7 extends not only over the exposed face of the lens, but also as pari-icuieriy iiiustruted in eoiirieetioii with Fig. WL exiends around be beveled or frame engagiiw edge S oic tbe iene aiifiviiie between die ieiis and the encircling frame i forming e Sori of cushioning :member to eiio'w be. lens ro Yieid slightly under shocks therengzi-iust, iesseniiig the liabilityY of breakage or of piercing if the. object sriking the iene should breek it and. at Jdie. seme time somewhat relieving the face of the entire Shook against the frame. in bzii the shook bas been absorbed to a. certain degree before it is imparted to the frame 'iibe manner of forming my improved Yisnel member or iene has been pur-ioiiiarly iiiusriied iii eomieoion iih iV anni if, ai'ferriatire iiiebods being ooiiresringir iiiuszra'ed ir.
